Abstract
According to an example, an optical transmission device may include a spatial light modulator having a plurality of cells, in which different wavelengths of a light beam are to impinge upon different groups of pixels along a dispersion direction. The device may also include a driver mechanism to modulate, at a first frequency, a first group of the plurality of cells upon which light having a first wavelength impinges to impress a first frequency fluctuation onto a property of an output light including the first wavelength and to modulate, at a second frequency, a second group of the plurality of cells upon which light having a second wavelength impinges to impress a second frequency fluctuation onto a property of an output light including the second wavelength, in which the second frequency modulation differs from the first frequency modulation.
